Response of LaBr3(Ce) scintillators to 2.5 MeV fusion neutrons.
نویسندگان
چکیده
Measurements of the response of LaBr3(Ce) to 2.5 MeV neutrons have been carried out at the Frascati Neutron Generator and at tokamak facilities with deuterium plasmas. The observed spectrum has been interpreted by means of a Monte Carlo model. It is found that the main contributor to the measured response is neutron inelastic scattering on (79)Br, (81)Br, and (139)La. An extrapolation of the count rate response to 14 MeV neutrons from deuterium-tritium plasmas is also presented. The results are of relevance for the design of γ-ray diagnostics of fusion burning plasmas.

The scintillation yield and decay time of LaBr3 doped with 0.2%, 0.5%, and 5% cerium were studied between 80 K and 600 K. LaBr3 :5%Ce 3+ on a photomultiplier tube shows at 300 K a very high scintillation yield of 22 800 photoelectrons per MeV 64 000 photons per MeV with a decay time of 16 ns. At 600 K the yield decreases by 15%. The scintillation yield of LaBr3 :0.2%Ce3+ is 19 800 photoelectron...

This study aims to investigate the potential use of LaBr3:Ce and LaCl3:Ce materials in SPECT imaging. GATE Monte Carlo simulations of single-head gamma camera and a Tc point source were performed to evaluate the energy spectra, modulation transfer function (MTF) and detection efficiency. A range of Ce concentrations (0.5, 5, 10 and 15)% of LaBr3:Ce and LaCl3:Ce crystals was simulated in conjunc...

Crystal growth and detector fabrication technologies have reached such a state of maturity that high-quality large-volume CeBr3 scintillators can now be produced with dimensions of 2′′×2′′ and well above. We present a study of CeBr3 samples of various dimensions and show that they have a number of advantages over equivalently sized LaBr3:5%Ce for gamma-ray spectroscopy applications requiring hi...

A system based on a LaBr3(Ce) scintillator and digital data acquisition is discussed in view of γ-ray spectroscopy measurements on a fusion burning plasma. High energy resolution and high rate capability of the system are demonstrated in laboratory tests and in dedicated experiments at nuclear accelerators. Preliminary results on sensitivity of the detector to 14 MeV neutrons are presented.
